Isolation and characterization of benzene, toluene and xylene degrading Pseudomonas sp. selected as candidates for bioremediation

Two-step treatment of harmful industrial wastewater: an analysis of microbial reactor with integrated membrane retention for benzene and toluene removal

“…The residence times were 135, 148, 196, 220 and 248 h. For two residence times of 135 and 220 h, a process with both substrates in the reaction mixture was also conducted. The kinetics of their degradation appears independent (that is consistent with literature reports 28, 29 ) and there were no synergistic inhibitory effects. The concentration values obtained for each pollutant were similar (mean relative error of 8.93%) to the concentrations obtained from the pollutant mixture (Table 1).…”

Influence of toluene and salinity on biosurfactant production by Bacillus sp.: scale up from flasks to a bench-scale bioreactor

“…Among the organic compounds, there are alkanes, cycloalkanes, benzene, toluene, xylenes, phenol and polycyclic aromatic hydrocarbons (Di Martino et al, 2012). Many of these compounds are considered to be extremely polluting because, besides being toxic, some of them have carcinogenic and mutagenic potential for human beings (Janbandhu and Fulekar, 2011).…”

“…Consequently, such highly-toxic compounds (except ethylbenzene) are the major causes of death related to drinking water contamination (Di Martino et al, 2012). Fellenberg (1980) reported that petroleum and its derivatives, when in contact with water, spread creating a thin film on the surface that prevents not only gas exchange between air and water, but also light from reaching phytoplankton, thus affecting the food chain.…”

Bioremediation of Toluene using Microbial Consortium Obtained from Industrial Effluent

“…Waste effluent generated from the petrochemical Industry consists of highly toxic derivatives of organic compounds like benzene, toluene, xylene and other poly aromatic compounds . Among, the mono-aromatic organic compounds, Toluene is widely used as a solvent in printing, paint, adhesive, cosmetic and plastic industry and is classified as a priority pollutant because of its high mobility and toxicity (Martino, 2012). As compared to conventional chemical or physical techniques of remediation which have inherent drawbacks due to high operating cost, difficulty in operation and production of secondary pollutants, Bioremediation which involves the use of naturally occurring microorganisms for biodegradation of toxins presents an alternative, yet better approach for the remediation of Toluene (Janbandhu, 2011).…”
